Fire protection water tank

Abstract

The invention provides a fire protection water tank which comprises a tank body, a rotating wheel and a generator. The tank body is provided with a water containing cavity. A water inlet pipeline anda water outlet pipeline are arranged on the two sides of the water containing cavity. The generator is mounted on the outer portion of the tank body. The rotating wheel is mounted in the tank body andis connected to a motor shaft of the generator in a sleeving manner. The rotating wheel is provided with multiple water guide holes. According to the fire protection water tank adopting the technicalscheme, when a fire fighting truck runs on a jolty road surface, the fire protection water tank strenuously vibrates, the water guide holes increase damping for water when a truck body jolts, and therefore water vibration is reduced; the rotating wheel can be driven to rotate, and therefore power generation is achieved; and the rotating wheel is utilized for carrying out drainage on water of thetank body, the water is prevented from fiercely impacting on the inner wall of the tank body, the fire fighting truck runs stably, and the service life of the fire protection water tank can be prolonged.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting water tank. Background technique [0002] A fire truck is a vehicle specially used for fire fighting or other emergency rescue purposes. The fire water tank on it is a water-carrying tank welded by sheet metal materials. The water injection of the fire-fighting water tank can be completed by the water pump on the fire truck. After the water pump runs, the water tank water filling valve is opened, and the water pump injects pressure water into the water tank. In addition, the external water injection pipeline can also be set separately. One end of this pipeline is connected to the top of the water tank, and the other end is equipped with an external water injection interface, and there is an external water injection valve that can be opened and closed. The water tank is filled with water. The volume of existing fire-fighting water tanks is getting...

AI Technical Summary

Problems solved by technology

The volume of existing fire-fighting water tanks is getting larger and larger, and the amount of water stored is also increasing. During the filling process of fire-fighting water tanks, the water directly enters the tank body, thereby hitting the inner wall of the tank, causing deformation of the tank body and shortening the fire-fighting water tank. The life of the tank and the mechanical energy entering the water flow is not fully utilized

[0003] In summary, during the water injection process of the existing fire-fighting water tank, the water flow enters the fire-fighting water tank and impacts the inner wall of the tank, causing damage to the tank body, and the kinetic energy and potential energy of the high-speed entering water flow cannot be well utilized. In addition, the fire-fighting water tank When the car is driving on a bumpy road, it will vibrate, and the water body in the tank will also vibrate accordingly, which makes the fire truck run unstable, and the water flow hits the inner wall of the tank, which will also affect the service life of the fire water tank
